For this, hydration is essential. The average non-athlete should consume about half a gallon of water a day; This can come directly from drinking liquids, or it can come from liquids that are naturally found in foods. The recommendation for athletes is to divide their weight in pounds by two and consume one ounce of fluid per pound. That would mean 100 ounces (just over three liters) for a 200-pound athlete. Hope your grandson has a healthy diet, is otherwise in good health, and stays well hydrated (his gallons per day can be a little too high). His body weight and exercise practices should support his protein intake. That should also apply to his customers. There is a good discussion about the protein needs of athletes at b.link/hfbvzz.
Dear Doctor. Blonz: You see all of these “special” bottled water that is ionized, bubbly, or otherwise, and their claims that they are better for you than plain tap water, even filtered. Am I wasting my money buying these products? – PS, by email
Dear PS: If the water, however treated, makes it more comfortable for you to drink, then go for it. But assuming no substances have been added, everything is just water. When making claims, there must be objective evidence, i.e. using scientific methods, from those who have no financial interest in the product.
